Abergavenny

Wales - United Kingdom

Located in southeastern Wales
on the English border, Abergavenny is a
market town that was once home to fortresses for the Roman and, later, Norman empires. This is where the
Knight Bus dropped Madam Marsh
off the first time Harry rode it in PA3.

Acanthia Way

Little Norton - United Kingdom

Ackerly Town Hall

Ackerly - United Kingdom

This town hall was the site of a concert which included the final performance of the unfinished
Wizarding Suite, composed by
Musidora Barkwith. The exploding tuba featured in this
concert blew the roof off the Ackerly Town Hall in 1902,
and the piece has been banned from performance ever since (fw36).

Aeaea

Greece - Europe

Aeaea was a legendary island during ancient Greek times, and may or may not have actually existed off the coast
of Greece, if at all. It was the home of the famous sorceress
Circe (fw3).

Africa

Locations in Africa:

Albania

Europe

Albania
is a European country located along the coast of the Adriatic Sea. Not long
after Hogwarts was founded, the country inadvertently played a part
in wizarding history when Rowena Ravenclaw's daughter
Helena stole her mother's diadem and ran away to Albania. Though
she later returned to Britain, the diadem remained hidden in a hollow
Albanian tree, presumed lost for all time (DH31).

In the summer of 1991, Professor Quirrell, then the Muggle Studies teacher at
Hogwarts (BLC), happened across
Voldemort in his hiding place in the Albanian woods. It was here that
Voldemort convinced him to work for him and take him back to Britain
in search of the Philosopher's Stone. When that
quest failed, he returned to Albania to hide in the woods once more
(GF33).

alley behind the Leaky Cauldron

Diagon Alley - London - England - United Kingdom

"Hagrid led them through the bar and out into a small, walled
courtyard, where there was nothing but a dustbin and a few weeds.... He tapped the wall three times with the point of
his umbrella. The brick he had touched quivered - it wriggled - in the middle, a small hole appeared - it grew wider
and wider - a second later they were facing an archway large enough even for Hagrid,
an archway onto a cobbled street that twisted and turned out of sight. 'Welcome,' said
Hagrid, 'to Diagon Alley.'"
(PS5)

Though nondescript, this alley is one of the primary gateways in
Britain from the Muggle world
into the wizarding world. It has rarely been mentioned since
Harry's first time through, but presumably wizards need to pass through it any
time they travel between the Leaky Cauldron and the rest of
Diagon Alley. It's interesting that magic is required to pass
through it when it seems Muggles can't see the Leaky Cauldron
to begin with (PS5).

Argentina

South America

Argentina is the second largest country in
South America and features a
little bit of everything, from mountains to coastline. Its national Quidditch team reached the World Cup quarterfinals
within the last century (QA8).

Argyllshire

Scotland - United Kingdom

Arjeplog

Sweden - Europe

A small city in the foothills of the mountains in northern Sweden, Arjeplog has for
over a millenium been the location of the finishing line for the
annual broom race of Sweden
(QA2). It is also less than three hundred miles away from a
Swedish Short Snout dragon reservation, which is most likely in the
higher parts of the mountains.

Asia

Locations in Asia:

Assyria

It's unclear why Neville uses the term Assyria to describe a region that no
longer bears this name, but Assyria is nevertheless a region in the Middle East mainly including modern-day Iraq,
Syria, and Lebanon - though the Assyrian empire once stretched well into Iran,
Turkey, Israel, and Egypt as well. Whether
Neville uses the term to describe the region or whether wizarding governments recognize different borders and
country names from their Muggle counterparts, this was where his great-uncle
Algie got Neville's
Mimbulus mimbletonia
(OP10).

Australia

Australia
is both the smallest continent and its own country, located on a large island entirely in the southern hemisphere.
Hermione sent her parents to
Australia during the height of the war against Voldemort, to protect
them from Death Eaters. She also modified their memories so they did
not remember she existed (DH6). After Voldemort's final defeat she
returned to retrieve them once more (BLC).
